Specification of Letters Patent.

Patented. May 9, 1916.

Application filed February 4, 1916. Serial No. 76,108.

To all whom may concern:

Be it knownthat I, GEORGE W. MOHR, a citizen of the United States, and aresident of Jersey City, in the county of Hudson and.

State of New Jersey, have invented certain new and useful Improvementsin Port-Hole Ventilators, of which the following is a specification. i

The object of this invention is to provide a means whereby the ports ofships or the like may be left open in rough or stormy weather, butwithout permitting the entrance of water, whereby ventilation may be hadWithout end a casing is provided at the inner side of the port, having atight door giving access to its interior and transparent means in itsWalls to permit the free passage of light into the ship, this casingaccommodating and permitting the movement of the usual or suitable portclosures, and having automatic means, such as a float cooperating with aseat to ermit the passage of air into the vessel W ile preventing thepassage of water,

when said door is closed. After passing such automatic means, the aircurrent is preferably causedto flow through acircuitous coursedetermined by baffles or the like, which further prevent the entrance ofwater into the vessel andwhich trap any moisture carried by the airbefore the latter emerges into the portion of the ship to be ventilated.A screen between the first chamber or box of the casing and the floatchamber prevents the, latter and the baffle passage becoming obstructedby seaweed and the like. These and other features of the invention, willbe come apparent as the specification proceeds, reference being had tothe accompanying drawings, wherein:

Figure 1 is a view of the front elevation and partly in verticalsection; Fig. 2 is a vertical section taken in a plane at right anglesto that of Fig. 1; Fig. 3 is a horizontal section on the line 3-3 ofFig. 2; and Fig. 4 is a view partly in front elevation and partly invertical section of a modified construction. I 1' The outer wall of theship is represented at 1, 2 being a port and 3 the port frame. As iscustomary, the port maybe closed by a hinged port-light 4 alone, or bythe portlight in conjunction with an opaque shutter These two elementsmay be of any ordinary or suitable construction, and are accordingly notillustrated, in detail. The

the usual drawback. To this device partly in Y light 4 is hinged at oneside, as indicated at 6, and held hermetically closed by a clamp lock 8,of known construction. The hinge 'Z of the opaque shutter is shown atthe top, as

is usual, but instead of a single clamp look I prefer to provide thisclosure with two locks 8*, located toward the sides and above thebottom, so that the bottom of the box, about to be described, may bebrought as close as possible to the bottom of the port hole.

At the inner side of the'port is secured a casing, of which the firstchamber is formed by a box 9, this box being of suitable size and shape,but large enough, in any event, to accommodate the port closures 4 and 5and to ermit them to be swung open and closed.

he walls of the box carry glass panes 10, and the front is adapted to beopened and closed by an inwardly opening hinged door 11, which alsocarries a pane of glass. This door affords access to the port closuresand when. open permits of direct ventilation. It is made tightagainstleakage of water in any suitable or approved manner, such as isadopted inconjunction with the port-lights themselves, and is clampedshut by a locking device 12. It .will also be,understood that the bodyof the box itself, the mounting of its panes of glass, attached to thewall 1 are to be rendered water-tight by any of the known means andexpedients adopted for such purposes.

On top of the box 9, in Figs. 1 and 2, there is a further inclosure 13,which affords a passageway for air from the interior of the box to thestateroom or other space in the and the joint where it is ship to beventilated, means being provided,

however, whereby this passageway is closed or obstructed to water, sothat the latter may not enter the ship. The interior of this inwith theaction of the devices about to be described.

When the iron shutter 5 is opened, it is supported beneath the screen14. by a suitable catch indicated at 36, in which position it does notsubstantially obstruct the flow .'.of air into the inclosure 13.However, it is to be understood that I do not limit myself' Ito hingingthis closure at the top..' In like manner, the light 4, which is's'hownhinged- 5 exactly at the side, may be hinged elsewhere,

if desired. As the parts are arranged, it will- P be understood that thelight swings open ail-4 "jacent one side wall 'ofthe box, while the door11, when open, lies adjacent the oppo.--

. v.From theforegoing it willbe understood that under weather conditionswhich would otherwise require the port to be closed, the

closure 13 and thence into the ship. Any body of water which gainsadmission. to the chamber 15 beyond the screen 14 is prevented- Thelower part of the inclosure 13"- com prisesa float chamber 15,havinganex1t 16,; of large area, through the partition 17 In sures 13containing the float and float chant:

vis1on'therein of a suitable number oi-baffles. '1

A suitable door 35. afli'ords access to the usual closures land 5 may beboth opened, and, the door 11 being closed, no water will find its wayinto the ship, the air, however, being. free to pass through the box 9and infrom passing farther by the float 20,; which] automatically closesthe opening 16, and when the rush subsides the water drains back iiitothe tight box below, vand thence out through the port-hole; In additiona drain may be provided, as indicated at 32, leading to a-suitablepointof discharge; Spray is I t hrowi1 back by. the cap 24 asdescribed,andiso any watery-which Imay succeed inpassing through the,exit from the float v chamber; is

revente'dby the baflles from escaping from in lo' l J These bafflesalsorelieve the air currentkof? any free moisture which it"carries. It willbe understood, of. course, that these devices {will act also to keep out"snow; In, fair weather the doorll isopened, as well. as the. "portclosures 4 and 5,-theventilation'then being direct from the part throughthe box to .the interior of the ship. I

The construction shown in Fig. 4'is' similar to that just-described,except-that the incloher and baflles is atone side of instead of abovethe box 9*, as may be preferable in oer tain cases. With thisconstruction Iiprefer l to provide the box with a lateral extension 9"also having transparent .walls, so that ;1 00 adequate lighting isinsured. The screen 14*, instead of being. placed horizontallyat the topof the box, as Figs. 1 and 2, is disposed vertically betweentheinteriors of" the :chamber, thereby insuring the operation .of thefloat. Otherwlse the construction-is sub stantially that i alreadydescribed.-

. Inconclusion I wish it to be-understood a 1 that I donot limitmyselfjto the form, prO- portions orthe specific devices illustrated, and thatnumerous changes may bemade and equivalents substituted without depart-.ing from the essentials of the invention.\

For example, while I now deem it preferable to. employ a float valveofthe character illustrated I do not necessarily limit myself thereto,since other devices may be "used for performing the samefunctionsin'substantially the same way. lt will be obvious also that theinvention may be used in lighthouses and in other locations whereconditions are similar to those on boardship.
